ICE-DELIVERY MECHANISM.

25 designates scraper bars which are pro vided with scraper arms 26 and handles 27, the arms 26 lying in contact with the in clined walls 3 of the hopper so that, when the bars 25 are reciprocated, the arms 26 will scrape the frozen material from the inclined walls, if such there be. I

I prefer, however, to operate the bars 25 mechanically and this may be done through a connecting lever 29 fulcrumed at 30 to a bracket and pivoted at 28 to the bars 25, the connecting bar 29 being oscillated by a bell crank whose long arm engages the bar 29 and whose short arm 31 is connected by a pitman 34: with a suitable cam device 35, by which the necessary reciprocating motion may be imparted.

While I have shown one specific embodiment of my invention, I desire it understood that modifications of the same in the arrangement of parts and details of construc ing downwardly from the entrance, said hopper having a bottom consisting of converging side walls leading to a conca ity, a propeller located in said concavity, said hopper having a discharge throat to which said propeller delivers the contents, an agitator cooperating with the propeller for reventing ice bridges adjacent to the prope ler,

reciprocating scraper bars operating over the converging walls of the hopper, means for rotating the propeller and agitator, and means cooperating with said rotating means for translating the rotary motion into a reciprocatory motion and reciprocating said scrapers;

2. In ice delivery mechanism, a hopper having inclined bottom Walls and a bottom teed trough, a feed propeller in said feed trough, scrapers in the hopper operating over the inclined walls to dislodge the ice from the inclined Walls, an agitator shaft in the bottom of the hopper paralleling the feed propeller and having radial arms projecting into the path of rotation oi the propeller between the blades thereof for preventing ice bridges.

In ice delivery mechanism, a hopper comprising an upper section and a lower section, the lower section comprising inclined bottom Walls and a feed trough'having a dischargeoutlet, the upper portion of the hopperhaving its walls convergin toward the top, whereby the entrance to the hopper is of less cross sectional area than that portion adprcent to the inclined walls, a propeller mounted within the feed trough for forcing the ice to the outlet opening, means within the hopper for agitating the ice to prevent the formation of ice bridges, scrapers mounted in the hopper onthe inclined walls for loosening the ice from the inclined walls, and means for operating said propeller, said agitators and said scrapers.
